This has been a great, dependable wireless router. I finally retired the previous D-Link 802.11G router to my mother's home when she finally got DSL (and it is still running great#. I have configured and used this router with a pass through to the ports to my web server without issue and ran it on low transmit power until more neighbors bought wireless and had to crank it up to high power to get a clean signal in the house. I was trying to find out how old this router is, and looked on the label to find HW Ver. A2 FW Ver. 1.11. Firmware version 1.20 per this web site, came out in 8/14/2008. After some more looking, I downloaded a later manual that has instructions on how to configure IPv6. Unfortunately, this one is too old to be upgraded to IPv6, but since almost all of my machines answer pings in IPv6, I will go and buy a newer DIR-655 so I can have it do the DNS for the new TCP/IP standard. Yes, I work in computers, yes I have it sitting on the top of a shelf with good airflow around it, and yes I have a #new) 8 port Gb switch hanging off of it to connect my lab computers. I have only 2 boat anchor computers that are older than this router. It just works and mom will end up with this one when I buy a new DIR-655.
